and useful Improvements in Automobile I Fans, of which the following is a specifics tionl.. This invention relatesto cooling "tans for 1 automobiles and more particularly to a novel and improved design of fan whereby the maximum amount-oi air may be ob tained to positively cool the radiator and engine. j

The primary object of the invention rcsides in the provision oi" a novel and improved automobile. fan having a plurality oi equally spaced blades preteraliily seven in number, and one designed for use in connection with Ford automobiles as a substitute forthe standard fans now being manufactured. A I A still further and very importantobject :Olli the invention resides in the construction of an automobile tan wherein the radially disposed blades are constructed and 1 an ranged in a manner whereby the maximum amount of air willbe drawn into the body oi the machineand prevent the engine from being overheated, the parts of the fan structure being very simple in construction, easily assembled, rigid and durable, highly etli cient in operation, practical yet capable of being manufactured at a very low cost 1 35, whereby its commercial possibilities are greatly enhanced.

With these and other objects in view, the invention consists inthe construction or the novel combination, and arrangements at parts hereinafter fully described, illustrated with the accompanying drawings and point through the parts above mentloned permit ed out in the subjectmatter being claimed, it being understood that various changes in the forms, proportion, size and minor details of construction within the scopeof the claims may be resorted to without departing from the spirit of the invention or sacriiicing any of the advantages thereoi".; y in the accompanying drawing i i F 1 is afront or itace view of the fan, Fig. 2 is a. side view talren'on a line 2- -2 of Fig. 1,

. Fig. 3 is a further view taken on line 3--3- of Fig. 1.

Referring nowto the drawings wherein like characters designate corresponding partly in section parts throughout the several. views, 5 designatesthe hub and 6 the flanged pulley for receiving the usual: driven belt (not shown) forrotating the fan as is well understood.

Cthe hub and pulley arepreferably formed integral with an annular, blade attaching plate 53 positioned centrally of a tan, said plate having connected thereto the tan including a central disk-like portion A 'integrally formed with plurality of radially e ztending blades 9, preferably seven in number whereby the 'maximum amount of air may be drawn intothe body of the machine to cool the radiator and engine. The respective blades 9 taper outwardly from their center where they areconnected by suitable screw bolts or other fastening ele ments 10, the sides 11, 12 of said blades being curved so as to extend beyond the inner 7 5 and outer planes of and below the plate 8 which are connected to the disk-like portion of the fan in the manner clearly shown by Figure 1 oil the drawings. Concentrically of the central disk-like portion A, is "an annular rolled rim 13, connected with the respective blades by a narrow web B. it will be observed that the tips or outer ends of the blades 9. are spaced. from the bead-like im 13 and are integrally joined therewith,

through the medium otthe web B. it will be obvious that the :lan proper can be cut and stamped from a single piece of material.

A reinforcing spider 14 having a plurality of the arms 15 attached thereto are riveted or otherwise secured as at 16 to each of the blades, the said fastening elements 10 extending through the plate 8, blades and spider thus providing a firm and rigid structure andpreve-nting the possible tlracturing of any one of the blades of the fan.

The fastening elements 10 extending of the attachment of my improved blade structure to the hub and pulley of the present type of fan now being used on Ford will be obvious however that other emhorliments may be adopted and that various changes in the (let-ails of construction may he resorted to by those skilled in the art Without departing from the spirit and scope of the invention. It is furthermore understood that the invention is not ]1CGSSfl1'll Y limited or restricted to the precise elements shown except in so tar as such limitations are specifier l in the subject matter being claimed.

Having shown and ilescrihecl my invention, what I now claim as new and (lesire to secure by Letters Patent of the ll. 3. is

1. An automobile l -Lin Wheel. comprising a single sheet metal hlenk cut and bent to provide a circular series oi hlailes integrally joined together by a disk at the hub portion of the Wheel and integrally joined about the periphery by t circular rolled rim, the blades, with the whole tan structure being in one piece and each blade having a radially twist increasingin (legree from the huh to the rim port-ion flllli ilisheil symmetricall i with respect to the l'ront face oi" the l)l:l(l(.

2. in automobile tan Wheel, comprising a single sheet metal hlank cut and hent to pro YlLlO a circular series of hlailes integrally joined together h) a (lisl; at the, huh portion oi the wheel and integrall joineil about the peripherv h i' a circular rollerl rim. the hlzules, with the whole tan structure heing' in one piece ainl each hlaile having; a railially twist inc easing in ale rree from the huh to the rim portion and (lielierl synunelrically with respect to the trout 'lace ol' ihe hlailin one of the edges of all the hlailes l)llllf locatezl in suhstantiall one plane :unl the other mines of all the hlarlee ilistanl l'rona the first nanic l (.(lflt heinn ol' progressively inc easing distance lroni saiil plane.
